Federation outpost near Sherman's Planet, located one parsec from Klingon space. A Federation development
project for Sherman's Planet in 2267 was threatened when 1,771,561 tribbles infested storage bins of
quadrotriticale intended for the project. Unknown to anyone at the time, a former Klingon agent under the alias
Arne Darvin, travelled back from 2373 to 2267 using the Bajoran Orb of Time to kill Captain James Kirk and
change his own history. The crew of the USS Defiant NX-74205 used the
orb to stop Darvin from altering history.

Although Deep Space Station K-7 was near Sherman's Planet, an area first explored in 2067 by John Burke, it was
a free-floating structure that was not in plantary orbit. Its main section was shaped like a flattened sphere
with a thick center that tapered to a point at the edges, and was the area of the station that contained most of
the storage compartments. Above the main section was a dome where the leisure and living facilities were located.
On top of this was a long, thin structure that was a communications mast. Thin tubular arms attached the three
smaller saucer sections to the main hub, and at the bottom of the space station there was a shuttlebay. The
station had some leisure facilities, and its main attraction was the bar which also sold exotic merchandise and
souvenires. Day-to-day operations on K-7 were supervised by Mr. Lurry. Middle-ranking bureaucrats, such as
Nilz Baris, were also been based on the station.

Stock footage of K-7 was later reused in "The Ultimate Computer" (TOS), although it represented another
station.
